The slot29 has a widened mouth 30 withinwhich the screw-eyes are received as they travel downwardly along therod 27.r

To aid in this movement of the screw- 'cyes along the rod 27,accelerators, in the form of brushes 31 are located 4upon 0pposite sidesof the rod, these accelerator brushes being secured to the end of shafts.32 mounted in a diagonal position in bearings 83 in the bracket 5, saidshafts having" .intermesliing pinions 34e by means of which they/aredrivenin opposite directions and one of said shafts having a drivingsheave 35 `around whichy a belt extends, said belt passing around idlers36 mounted in beany ingsV diagonally arranged on the ybracket 5 to aslieave? secured to the ,feed shaft 15, and as shown in Figure 2 of thedrawings.

i 'A forkedk ykicker 38 is secured to a kicker 4shaft y39 mounted iii anupward extension of the bracket 5 and having a gear segment 40v meshingwith a gear segment I1-1 pivota'lly mounted upon a pin 42 and having anactuating linger 4:3 projecting into the path of' movement4 of sweeps14; projecting from the edge of a disc secured to the shaft 15. The,linger 13 is held in its normal position ofrest as by means of a spring46Y pressing against a pin 47 projecting from Vthe side of the lingerand' forcing said pin into con-v tactwith ay stop V48. Y

`The oper-ation of the device will be readily understood, it being notedthat as the feed `fingers 19lor receivers are moved through a mass ofscreweeyes located in the hopper 8,

more or less of said screw-eyes will be picked up by the lingers andwill rest against 'thefV shoulders 2O thereon. As the screw-eyes arecarried outwardly should. they chance to'pio-` ject vupwardly they willcome in Contact with the adjuster 23 by means of which they will beswung on the finger and by the ac-v tion 'of gravity to a verticalposition. As the fingers approach the end of the guide rod,v 27 theAscrew eyes will fall on to said guidev rod as "shown in Figure 1 of thedrawings andthe rotation ofthe accelerator brushes 31 will passthe'screw eyes along the rod .into the mouth 30 of the aligner 28 bymeans 'j of vwhich'said screw eyes will be adjusted with their slianksall in alignment ready for delivery to devices for receiving them.VShould an excessive number of screweyes be accumulated upon the guiderod 27 the kicker 38 will remove the surplus, and thus keep Athe end ofthe rod so that Iit will not interfere with the movements of the v tipsot` thel spring lingers past the poiiitjof the guide rod. The hopper plyscrew eyes faster than the rest of the mechanism* cank use them,`this inorder to insure constant supply, and the kicker.,

is arranged to sup` therefore, acts as a regulator to control the supplyand thereby prevent an over accumulation upon the guide rod.

The bottom of the hopper 8 slopes downwardly from the center toward theperiphery thereof for the purpose of collecting a mass of articleswithin a certain portion of the hopper, and the lcollector 22 is.spirally formed to assist in this. operation. The screw eyes are thuscollected in a mass and this resnltis yfurther aided by the rotatingmovenient of the hopper. An accumulated mass ot' screw eyes istliuslocated in the path of movement of the lingers 19 to insure Aat v alltimes the elfective'picking up o-f the screw yes by said'tingers. Thehopper is preferably rotated in av direction vto cause the screw eyes totravel toward the feedfni gers19.,V

The guide rodv 27 extends through the aligner 28 and is constructed to'yieldingly retain the screweyes in place' at its lowerv-` end, thealigner inv fact constituting a magazine to receive the `screw eyessupplied'to it by the fingers 19. The rod is loosely mount-V ed in thealigner, or magazine, and when the screw eyes are locatedjupon it, it isspaced from the inner that the invention may be carried out by othermeans and applied to uses other than those above set out;
